And I check. While kamailio process REGISTER request $avp(i:123) value equals table column call_limit.

But after that while it process INVITE request $avp(i:123) is <null>

Thank you, Daniel

I am trying to do this.
modparam("auth_db", "load_credentials", "$avp(i:123)=call_limit")

After auth:

This from mysql log:
2016-10-18T07:14:02.598195Z     4451 Query    select `password`,`call_limit` from `subscriber` where `username`='2000'
2016-10-18T07:14:02.599166Z     4451 Query    select `username` from `subscriber` where `username`='' AND `domain`='172.21.0.150'

But when i want to see value of this avp in route[DIALOG]:
xlog("L_INFO", "Control Active Calls $avp(i:123)");

I call from 2000 to another peer аnd recieve null:
Oct 18 11:14:38 kamailio /usr/sbin/kamailio[11470]: INFO: <script>: Control Active Calls <null>

Hello,

you can use sqlops module to load data from database and store in an xavp.

If you want to load from subscriber table along with auth credentials, look at load_credentials parameter from auth_db module.

Cheers,
Daniel

Hello!

I am trying to implement limit of active calls for subscribers. And for each subscriber this limit must be personal.

I find example route in presentation of Daniel-Constantin Mierla.
And i need to set $xavp(caller=>active_calls) = 1;

for each dialog. But i can't understand how to load this number of active calls from some-thing similar of user profile or subscriber table?

route[DIALOG] {

    if (is_method("CANCEL") || (has_totag() && is_method("INVITE|BYE|ACK"))) {
        dlg_manage();
        return;
    }

    if (is_method("INVITE") && !has_totag() && !isflagset(WITH_ACTIVE_CALLS_LIMIT)) {
        if( $xavp(caller[0]=>active_calls) != $null && $xavp(caller[0]=>active_calls) > 0 ) {
            if(!get_profile_size("caller", "$fU@$fd", "$var(acsize)")) {
                send_reply("500", "No more active calls");
                exit;
            }
            if($var(acsize)>=$xavp(caller[0]=>active_calls)) {
                send_reply("403", "No more active calls");
                exit;
            }
            set_dlg_profile("caller", "$fU@$fd");
        }
        setflag(WITH_ACTIVE_CALLS_LIMIT);
        dlg_manage();
    }
}
